Input Power
DC PSU can be switched on or off using a switch on the front panel of the DC PSU.
Note
For DC PSU, the UVP and OVP limits vary depending on the input voltage applied at power up:
Note
For -48/-60 V: UVP= -36 Vdc and OVP = -72 Vdc
For 24 V: UVP =18 Vdc and OVP = 32 Vdc
This product requires surge protection as part of the building installation. To comply with the Telcordia
Note
GR-1089 NEBS standard for electromagnetic compatibility and safety, an external surge protective
device (SPD) is required at the AC power service equipment.
Note For DC systems, if a surge of more than 1KV is expected, add an appropriate external surge protective
device.
The Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router have removable fan tray
as part of the system. The fan tray is hot-swappable. The system is designed to operate at its maximum
operating temperature of 70º C and at 65º C in case of failure of a single fan, for a maximum of four
hours.

LED Indicators

This section describes the different types of LEDs and their behavior.
PWR and STAT LEDs
The PWR and STAT LEDs are available on the front panel. These LEDs provide power on the board
(PWR) and overall router health (STAT) status. During power up state, these LEDs provide booting
status and report errors.
The digital code signing functionality validates the integrity and authenticity of the ROMMON image
